Is Current Evidence That Avoidance Of Inhalation Agents And Opioids May Decrease Metastasis Strong Enough For Crnas To Show A Willingness To Change Practice?, Michael Wesley Tillman 2016 University of Southern Mississippi

Is Current Evidence That Avoidance Of Inhalation Agents And Opioids May Decrease Metastasis Strong Enough For Crnas To Show A Willingness To Change Practice?, Michael Wesley Tillman

Doctoral Nursing Capstone Projects

Metastasis following the surgical resection of primary site breast cancer is a medical issue, which plagues mastectomy patients. The intention of this project was to synthesize current literature in order to make a presentation and disseminate it to Certified Registered Nurse Anesthetists (CRNAs) in southern Mississippi and assess the providers' willingness to change practice. CRNAs took part in a Qualtrics survey after viewing a PowerPoint presentation of evidence regarding anesthesia and metastasis. The presentation illustrated the anesthetic techniques and pharmacological agents utilized, which either mitigate or potentiate a patient's risk for metastasis. The survey assessed for a willingness to ...


Photothermal Therapy Improves The Efficacy Of A Mek Inhibitor In Neurofibromatosis Type 1-Associated Malignant Peripheral Nerve Sheath Tumors., Elizabeth E. Sweeney, Rachel A. Burga, Chaoyang Li, Yuan Zhu, Rohan Fernandes 2016 George Washington University

Photothermal Therapy Improves The Efficacy Of A Mek Inhibitor In Neurofibromatosis Type 1-Associated Malignant Peripheral Nerve Sheath Tumors., Elizabeth E. Sweeney, Rachel A. Burga, Chaoyang Li, Yuan Zhu, Rohan Fernandes

Pediatrics Faculty Publications

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive tumors with low survival rates and the leading cause of death in neurofibromatosis type 1 (NF1) patients under 40 years old. Surgical resection is the standard of care for MPNSTs, but is often incomplete and can generate loss of function, necessitating the development of novel treatment methods for this patient population. Here, we describe a novel combination therapy comprising MEK inhibition and nanoparticle-based photothermal therapy (PTT) for MPNSTs. MEK inhibitors block activity driven by Ras, an oncogene constitutively activated in NF1-associated MPNSTs, while PTT serves as a minimally invasive method to ablate ...

Determining The Incidence And Factors Of Cardiotoxicity In Breast Cancer Patients Treated With Anthracycline And/Or Trastuzumab-Containing Regimen At Aurora Health Care, Stephanie Ghojallu, Matthew Rappelt, Han-Yang Chen, Ruth Perez, Lydia Garlie, Geoffrey Riddell, Yingying Gu, Jun Zhang, Rubina Qamar, Bijoy K. Khandheria, Arshad Jahangir, Yang Shi

Journal of Patient-Centered Research and Reviews

Background: Anthracycline and trastuzumab are common breast cancer treatments. While improving survival, they elevate risk of congestive heart failure. The incidence of cardiotoxicity (CTx) with these therapies varies in the literature from 10% to 59%, higher than those reported in clinical trials (4%–10%) that excluded patients with preexisting cardiovascular comorbidities. Studies have failed to establish consensus on the risk factors for CTx associated with these therapies.

Purpose: We aim to determine the incidence and risk factors of CTx in breast cancer patients treated with anthracycline and/or trastuzumab at Aurora Health Care.

Methods: A retrospective review of patients with ...

The Effect Of Luteolin On Human Glioblastoma, David M. Anson, Samson Amos, Robert L. Paris, Denise S. Simpson

Samson Amos, R.Ph., Ph.D.

Glioblastoma multiforme (GBM) is widely recognized as the most common and lethal of the malignant gliomas. Few effective therapeutic treatments are available as five-year survival rates of diagnosed individuals are less than five percent. Luteolin, a common flavonoid found in a variety of fruits and vegetables, has demonstrated significant promise in combating cancers of the breast, colon, liver, lung, and bone. In this study, we investigated the effects of luteolin on glioblastoma multiforme cell lines U-251, U-87, and U-1242. Cell viability was assessed using cell count with trypan blue exclusion and MTT assays. Results revealed that luteolin reduces GBM cell ...

Garden, Md, Randal S. Weber, Md, Jay S. Cooper, Md, Arlene Forastiere, Md, K. Kian Ang, Md

Bodine Journal

Purpose

Concurrent chemoradiotherapy (CCRT) for squamous cell carcinoma of the head and neck (SCCHN) increases both local tumor control and toxicity. This study evaluates clinical factors that are associated with and might predict severe late toxicity after CCRT.

Methods

Patients were analyzed from a subset of three previously reported RTOG trials of concurrent chemoradiotherapy for locally advanced SCCHN (RTOG 91-11; 97-03; and 99-14). Severe late toxicity was defined in this secondary analysis as chronic Grade 3-4 pharyngeal/laryngeal toxicity (RTOG/EORTC late toxicity scoring system) and/or requirement for a feeding tube ≥2 years after registration and/or potential treatment-related ...

Inhibition Of P73 Function By Pifithrin-Α As Revealed By Studies In Zebrafish Embryos, William R Davidson, Qing Ren, Gabor Kari, Ori Kashi, Adam Dicker Md, Phd, Ulrich Rodeck

Bodine Journal

The p53 family of proteins contains two members that have been implicated in sensitization of cells and organisms to genotoxic stress, i.e., p53 itself and p73. In vitro, lack of either p53 or p73 can protect certain cell types in the adult organism against death upon exposure to DNA damaging agents. The present study was designed to assess the relative contribution of p53 to radiation resistance of an emerging vertebrate model organism, i.e., zebrafish embryos. Consistent with previous reports, suppressing p53 protein expression using antisense morpholino oligonucleotides (MOs) increased survival and reduced gross morphological alterations in zebrafish embryos ...

A Cone Beam Ct-Based Study For Clinical Target Definition Using Pelvic Anatomy During Post-Prostatectomy Radiotherapy, Timothy Showalter Md, A. Omer Nawaz, Ma, Ying Xiao, James Galvin Phd, Richard K. Valicenti, Md

Bodine Journal

Introduction:

Radiation therapy (RT) is delivered after radical prostatectomy (RP) either as salvage treatment for an elevated prostate-specific antigen (PSA) level1-6 or as adjuvant therapy for patients with highrisk pathologic features7-8. Recent prospective data demonstrated a disease-free survival benefit of adjuvant RT for pathologic T3N0 prostate cancer9-10. Despite literature supporting the delivery of post-RP RT to the prostatic fossa (PF), no clear target definition guidelines exist for intensity modulated radiation therapy (IMRT) or image-guided RT (IGRT)11.

Visualization of the PF is limited on standard CT images, with significant interobserver variability and uncertainty in CTV definition12. Efforts to incorporate complementary ...

Flexible Needle-Tissue Interaction Modeling With Depth-Varying Mean Parameter: Preliminary Study, Kai Guo Yan, Tarun Podder, Yan Yu, Tien-I Liu, Christopher W.S. Cheng, Wan Sing Ng

Bodine Journal

Flexible needle steering has aroused a lot of research interest in recent years. It has the potential to correct targeting errors, which may be caused by needle bending, tissue deformation, or error in insertion angle. In addition, control and planning based on a steering model can guide the needle to some areas that are currently not amenable to needles because of obstacles, such as bone or sensitive tissues. Thus, there is a clear motivation for needle steering. In this paper, a spring–beam– damper model is proposed to describe the dynamics during the needle–tissue contact procedure. Considering tissue inhomogeneity ...

A Propensity Score Analysis, Timothy Showalter Md, Atul Rao, Rani Anne Md, Francis E. Rosato, Ernest L Rosato, Jocelyn Andrel, Terry Hyslop, Xia Xu, Adam C. Berger

Bodine Journal

Background:

Locoregional recurrence (LRR) is an important factor after pancreaticoduodenectomy (PD) for pancreatic cancer. IORT administered to the resection bed may improve local tumor control.

Methods:

We performed a retrospective analysis of patients who underwent PD at Thomas Jefferson University Hospital (TJUH) between 1995 and 2005 to identify patients who underwent resection with and without intraoperative radiation therapy (IORT). Data collected included age, gender, complications, margin status, stage, survival, and recurrence. Unadjusted analyses of the IORT and non-IORT groups were performed using Fisher’s chi-square method for discrete variables and Wilcoxon Rank Sum test for continuous variables. To account for ...

Nuclear Factor Κb Inhibitors Alleviate And The Proteasome Inhibitor Ps-341 Exacerbates Radiation Toxicity In Zebrafish Embryos, Borbala Daroczi, Gabor Kari, Qing Ren, Adam Dicker Md, Phd, Ulrich Rodeck

Bodine Journal

Inflammatory changes are a major component of the normal tissue response to ionizing radiation, and increased nuclear factor κB (NF-κB) activity is an important mediator of inflammatory responses. Here, we used zebrafish embryos to assess the capacity of two different classes of pharmacologic agents known to target NF-κB to modify radiation toxicity in the vertebrate organism. These were proteasome inhibitors, including lactacystin, MG132, and PS-341 (Bortezomib/VELCADE), and direct inhibitors of NF-κB activity, including ethyl pyruvate (EP) and the synthetic triterpenoid CDDO-TFEA (RTA401), among others. The proteasome inhibitors either did not significantly affect radiation sensitivity of zebrafish embryos (MG132, lactacystin ...
